To all whom it may concern:

Be it known that I, DALE MARSHALL, subject of the King of Great Britain,residing at 30 Winchombe street, Cheltenham, Glouces tershire, England,have invented certain new and useful Improvements in Wheels HavingSelf-Contained Motors, of which the following is a specification.

My invention relates to motor driven traction wheels and particularly toa wheel of this character having a self-contained motor preferably ofthe internal combustion type.

The primary object of the invention is to provide an improved andpractical system of propelling motor vehicles, motor cycles, and suchcarriages.

A further object of the invention is to provide a construction which maybe made and sold on the market in the form of a wheel with aself-contained motor whereby it may be purchased independent of thevehicle to which it is adapted to be applied, and incorporated in anexisting vehicle by substituting it for one or more of the existingtraction wheels.

0 Further objects will be apparent upon reference to the accompanyingdrawing, 1n

which Figure 1 is a perspective view of a wheel illustrating theinvention as incorporated therewith;

Fig. 2 is a sectional view of the moto and its associated parts.

Fig. 3 is a cross-sectional view of the motor, taken immediately abovethe silencer M.

Referring to the drawings, in detail, A represents the collar-shapedcylinder and B represents the collar-shaped piston adapted to work inthe cylinder A. The cylinder is mounted upon and adapted to rotate aboutthe axle or shaft C. This cylinder also provides a hub D for the wheeland is constructed with flanges E to which is attached the spokes of thewheel which spokes carry the usual rim on which is mounted the tire F.The mounting for the cylinder on the shaft C comprises ball bearin s G.The piston B works in the cylinder 3 longitudinally of the axle or shaftand is constructed to giye axial rotation to the cylinder A which inturn imparts the necessary drive to the wheel, the cylinder being a partof the wheel by reason of the spokes being fixed to the flanges carriedthereby. If desirable, the axle or shaft C may be connected to the crankshafts H H, of the piston B and in this event the crank shaft will havea geared or like engagement with an annular mem ber J mounted at theside of the wheel. When it is desirable to impart a rotative movement tothe axle or shaft 0 instead of directly to the wheel, the hub orcylinders are secured against rotation. Fly-wheels K K are provided onthe crank shafts H H Around the cylinder walls are provided waterjackets L L which are employed for cooling purposes, or, if desired, thecylinder may be air-cooled in which event, usual radial flanges areprovided. Outside of the jacket L is provided an annular chamber Madapted to receive and serve as a mufliing means for the exhaust; asuitable passag T connects the cylinder with the muflier. The carburetedfuel is taken into the working cylinder through the axle or shaftbearing and crank chamber N through the ports V V and V For purposes ofignition electric current for causing the spark is connected to asuitable spark plug 0 mounted in the top of the working cylinder withits top so arranged that it will have a wiping contact with a live ringP.

aving thus described the nature of my invention, what I claim is 1. Inwheels containing motors which use a piston within a cylinder as part oftheir construction, the combination of a wheel hub formed to serve as apower cylinder, of collar-shape with peripheral flanges and soconstructed as to centrally accommodate the carrying shaft or axle aboutwhich it is intended to operate, and a iston of like shape within thesaid cylinder moving lengthwise to the carrying shaft connected so as togive rotary motion to one of the co-acting members.

2. In power units, as in claim 1, the said collar-shaped pistonconnected to transversely situated crank-shafts, an extension of thesaid wheel hub in which the crank shafts are rotatively carried, whichcrankshafts have geared connection with an annular member fixed toadjacent parts of the central shaft or axle and provide-by lar fixedring for continued contact with their propulsive movements,rotary-motion th ignition plug through which the electric to one of theco-acting member s. current may flow. 7
